Look at the code
<form id="payForm" action="yeepaypay.html" target="_blank" method="post" onsubmit="return checkform();"> 

The onsubmit function in the example is the function that fires before the form is submitted
function checkform() { 
var value = $("input[name='payWay']:checked").val(); 
if (value == 1) { 
return false; 
return true; 

The form will only be submitted if it returns true, otherwise it will not be submitted
